How do I use country codes in HTML?

How many countries are there in HTML?

The 240+ countries are arranged in Alphabetical order. This document is a utility for people creating HTML forms and needing code for letting the user select a country. It also discusses some general problems with large menus so simple you can take it as copy paste and can use it anywhere.

If you don’t want to make it a dropdown, you can embed the picker inline right into a page. To make the country picker perform well with a great UX you can simply enable autocomplete for a search functionality or order and group the countries alphabetically.
